Newtown KDR — Single Contract, New Home
Knockdown rebuild in Newtown is precluded in practice, and I will be straight about it. This is the iconic Victorian terrace suburb — terraces on 100 to 250m² blocks along King Street, with Heritage Conservation Areas covering virtually the entire suburb. You do not knock down a Newtown terrace.
The real work here is restoration and extension: a sympathetic restoration of the Victorian frontage with a clever rear extension that opens up modern living, planned carefully against the party walls. That is the dominant scope, and it preserves exactly the value the suburb trades on.
The ground is Wianamatta Shale, so any excavation for a rear addition is designed off a real geotech. The Victorian stock almost always carries asbestos and lead paint, so a licensed strip-out leads any works.
We build fixed-price, licence HBL 487805C. For Newtown, the real conversation is restoration and extension — let me show you what is possible.
Buildana manages the complete knockdown rebuild process in Newtown — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

The iconic terrace suburb, handled honestly
Newtown is Victorian terraces on 100 to 250m² blocks, with Heritage Conservation Areas covering virtually the entire suburb — the terraces and the King Street strip are precisely the value. A knockdown is precluded in practice.
The dominant scope is a sympathetic restoration with a clever rear extension, planned carefully against the party walls on blocks this tight.
Shale and old materials
The Wianamatta Shale means any excavation for a rear addition is designed off a real geotech. On tiny terrace blocks, the structure and access need careful planning.
The Victorian stock almost always carries asbestos and lead paint, so a licensed strip-out leads any works.
